Thanks Nirmalya for your suggestion. WC 4 times in a week is difficult for me. I will try it twice in a week.Also, I have 5 adult cherry, 8 baby cherry and 2 assassin snails are there, I feed them tetrabits. I dont want to add fish because of shrimp.

Thanks for you suggestion subhendu. I am adding 0.5ml excel and can not see any problem on hair grass.also, my fert dosages is already low - 4.75 ppm K, 7.15 ppm NO3, .5 ppm P after water change twice weekly.. thinking to increase K as I can see some deficiency on plant leaves. need to add extra Fe as well for red plant.Photo period - 9 hrssubstrate - this is the main problem. amazonia is 2 years old and can not provide any food for plant, should i leave it or add some potting soil ? dont want to buy amazonia. I used normal garden soil before in other aquarium and worked very well!Current problem - little hair algae in hair grass which i am removing every 3-4 days. green layer on aquarium glass which I am removing manually twice weekly before water change. also,not happy with plant growth.

for algae control- up the PO4 levels to the limit where plants dont stunt. and lower the K levels to the point plants dont show deficiency. what is ur N level? try to add some co2 source for faster growth

earlier dosage was NO3 - 7.15 ppm, P - .5 ppm and K - 4.73. also, .5ml excel everyday. then 2 weeks back i removed all plant and added dart layer in substrate and replant them. also, increased K to 15 ppm and suddenly can see the rise of algae (fungus type all over the plant leave). thinking for a H2O2 bath. would it help? anything else i can do to get rid off this. btw, plant growths are good now but algae taking the control fast.
